Question about Tuuters Plastic test tubes with corks
"However, the plastic tubes should not be filled with liquids, as the cork cannot be pressed into the glass like a bottle." OK, I get it, nothing liquid. But how do you close the tubes properly, if not by pressing the corks in? Is the cork just for decoration and is placed loosely.
Helpful answer
I screwed the cork in a little bit and it worked fine. So it shouldn't be a problem to close it. And I wouldn't put any liquid in either. The cork doesn't look quite so tight. For me, the corks are about 5 mm in the glass and hold well.
